VALVE LIFTER.

Application filed June 28, 1922.

To all whom it may concern Be it known that I, HENRY G. Finer, a citizen of the United States, residing at. Plantsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in a Valve Lifter, of which the following is a specification.

My invention relates to improvements in valve spring lifters.

It is an object of my invention to provide an apparatus which is adapted to compress valve springs sufficiently to permit the removal of the stem pins.

A further object of the invention is to provide an apparatus which is adapted to engage one or two valve spring members, to raise the same and hold the springs under compression as long as desired.

A still further object of the invention is to construct a valve lifter, that is capable of lifting one or two valve springs, and hold them under compression, and the same time be so positioned as to permit unobstructed operation upon the valve.

Another object of the invention is to provide an apparatus that is adapted to compress the-spring in a straight line and'thereby prevent the buckling or displacing of the spring during the lifting operation.

Vith these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts as will hereinafter be fully described and claimed.

In the accompanying drawings forming a part of the description and wherein like numerals are employed to designate like parts throughout the several views Figure 1 is a top plan view of a spring lifter embodying the invention,

Figure 2 is a side elevation of the device before it is actuated,

Figure 3 is a side elevation of the device after it is actuated, and

Figure at is a top plan view of the cross bar member, and

Figure 5 is a perspective view of the carriage member.

In the drawings wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 5 designates a cross bar member which is shown as being of length enough to engage two adjacent valve springs, the same being provided with two transverse slots 6 extend- Serial No. 571,389.

ing inwardly from one edge thereof to approximately midway between the opposite side edges of the cross bar member.

The cross barmember 5 is provided with an aperture 7 positioned midway of the transverse slots 6; By reason of the aper ture 7 the cross bar member 5 is adapted to be slidably mounted on a post 8. The post 8 has a beveled end 9.

The numeral 10 designates an operating lever, mounted near the upper end of the post by means of a bolt 11.

For raising and lowering the cross bar member 5, a carriage 12 is provided, said carriage preferably formed from a strip of material. The ends of the strip are bent in spaced parallel relation to thebody 13 of the strip with the end 14 overlapping the end 15 forming a shoulder 16. The carriage 12 is provided with apertures 17 to adapt the carriage to be slidably mounted on the post 8.. The cross bar member 5 is mounted within the carriage 12.

A link 18 is provided to connect the lever 10 and the carriage 12. Byraising or lowering the lever 10 the carriage and cross bar members will respond in the same direction. To hold the carriage and cross bar member in their uppermost positiona swinging locking pin 19 is mounted on the part below the carriage.

A gage pin or brace 20 is provided to facilitate in holding the post 8 in a rigid vertical position by abutting the engine block when the beveled end 9 of the post is engaged with any stationary portion of a motor.

It will be understood, of course, that the precise construction of the device may have to be varied to conform to the different types of gasoline motors or internal com bustion engines.

The operation of the device is as follows:

The bevel end 9 of the post 8 engages a stationary portion of a motor. The cross bar member 5 is placed in a position where the transverse slots 6 will receive two adjacent valve stems, the cross bar member extending beneath the valve spring seats so that the seats may rest upon said cross bar member. The device will be in a position i as shown in Fig. 2 of the drawings. To compress the springs, the operating lever 10 is raised. The lever is connected to the carriage 12 which is slidably mounted on the post 8 by means of a link 18, therefore, when the lever is raised, by reason of the link the carriage is also raised, and in view of the fact that the cross bar member is positioned within the carriage, the latter also will be raised thereby compressing the valve springs. To hold the springs under compression, a locking pin 19 is brought into engagement with shoulder 16 of carriage 12 as is clearly illustrated in Fig. 3 of the drawings. A gage pin or brace 20 is provided to keep the valve spring lifter in a vertical position, so that the springs will be compressed in a straight line so as to avoid cramping or displacement thereof. F ig. 3 of the drawings clearly shows the position of the various parts of the device when in use.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts, materials, dimensions, et cetera, may be made as fall within the scope of the present claims.

Having thus described my invention, I claim V 1. A device for compresing valve springs, comprising a post, a valve spring engaging element slidably mounted on the post, means for raising said element on the post, and a support associated with the post adapted to engage the spring engaging element for maintaining the same in an elevated position, to maintain thespring in a compressed position. i

2. A valve spring compressor comprising a post, a carriage slidably mounted thereon, a cross bar member adapted to be slidably mounted on said post and supported by the carriage, and means for moving the car riageand cross bar member along the post.

3. A valve spring compressor of the character described comprising meansfor compressing valve springs including a post, a carriage slidably mounted on the post and formed from a single strip of material, the ends of said strip being bent in a spaced parallel relation to the body of the strip with one end overlapping the other forming a shoulder, a swinging lock pin on the post adapted to engage said shoulder to hold the carriage in an elevated position, and means for moving the carriage along the post.

1. A valve spring compressor comprising a post, a fulcrumed lever connected to the post, a cross bar member slidably mounted on the post, a carriage slidably mounted on said post and supporting the cross bar mem her, and a link depending from the fulcrumed lever nd engaging said carriage to move the same along the post.

5. A valve spring compressor comprising a post, a cross bar member slidably mounted on said post, a carriage slidably mounted on'said post and supporting the cross bar member, said carriage formed from a single strip of material ,the ends of said strip being bent in spaced parallel relation to the body of the strip, one end overlapping the other end forming a shoulder, said shoulder positioned in an offset relation to the post, a swinging locking member moiuited on said post below the carriage and adapted to be swung in an angular relation to the post to engage the sholder on said carriage to hold the carriage in an uppermost position on said post, and means for moving the carriage along the post.

In testimony whereof I aflix my signature in presence of two witnesses.
